Was looking around for a good "do it yourself" frame building jig... do you all have any suggestions on a good one, preferably inexpensive.

You don't need one you just need to learn to measure straightness. A surface plate to index off of comes in pretty handy.

HERE's (http://www.instructables.com/id/EAGXSQSF18DW8ZH/) Marc Pfister's simple jig built from 80/20 T-slotted aluminum extrusions (http://fandl8020.com/), and HERE's (http://www.frameforum.net/forum2/index.php?showtopic=4107) one built of 3/4" plywood.

Old tombstone or some other surface plate. V Blocks from Manhattan Supply along with shim stock. Weight on top of the tubes holds them down, blocks free to float. Can use over a full size drawing, although putting down bluing and scribing works better. Then a square lets you figure position on the tubes. For lugs or lugless, tack and flip over usually works pretty well.

Hmm, all good stuff.
If I were to go the flat plate route, would not that pose a problem of getting the braise all the way around the tubing and lug? I thought the jig held the tubes in proper position so you can get to both sides to braise?
I was thinking the plate steel base and strong magnets on v blocks. Maybe making a v block that has adj height.
edit- just read mandovoodoo, i got it flip it... didn't know if it would be safe to move not finished off

Look for the book the paterek manual, shows how to build simple jigs.

Oh man that book is perfect, I need a copy... but first need some money, 85.00
anyone got a used copy to sell?
Rent the film. Look on the other frame site. Compositepro has a new design he published plans for, and it's pretty cool.
One thing you want to do is match your building style to the jig, or even non-jig you are going to want. Look at the Paternek stuff for the brazing, lugs, and have a look at Anvil as an ideal for TIG. You need to get and idea for the whole process.

Which film?
i have been reading a lot about the brazing, I am glad I did, didn't realize you needed to mind what filler you used in relation to the tube properties.. i.e. heat treated tube, and air hardend tubes.
also while looking around at lugs, i found a set that is microfusion... what is that mean... I am guessing another process besides lost wax casting? Is that good or should I stay away from them, cause I really like them. but they are 50+ a set...

I think he was referring to Tim Paterek's frame building DVDs (http://www.timpaterek.com/videos.htm).

ah, my mistake... watched the clip, seems like a good idea.
has anyone rented it, would an online rental place have it? Or is someone willing to rent it to me... I could have it back in two days.
I would trade my surfboard making and glassing vids.
